The invention relates to a transposition shoving-finger return yield mechanism, in particular to an application of a cam level structure in the transposition wire production technology, belonging to the technical field of winding wire manufacture. The invention is characterized in that: a fixed frame is provided with a revolving support which is sheathed at the middle of an oscillating bar, the oscillating bar is opened with a first displacement groove, one end of the first displacement groove is provided with an ejector rod, one end of the ejector rod is fixed on the oscillating bar by a fixed column, the ejector rod is opened with a second displacement groove, the other end of the ejector rod is provided with an impact wheel which is fixed by the fixed column thereof, the ejector rod support is arranged on the ejector rod, and the other end of the oscillating bar is provided with a press piece. When the specification and radical of the transposition wire are changed, the invention can use an experimental formula Nomo table to adjust the position so as to ensure the appropriate yield stroke of the mechanism and the applied force in the vertical direction to the shoving-finger under different states, thus avoiding calculation and adjustment of personnel in the transposition positions and being capable of direct quantification on the displacement groove of the shoving-finger return yield mechanism.
